Developing Web Applications with ASP.NET 3 day training course from £885.00 plus VAT

This course introduces delegates to ASP.NET web forms, the web application framework that developers can use to build dynamic, data-driven web applications.

Delegates learn how to build web forms, to add controls, validation and security, to manage state and to interact with data sources (RDBMS, XML and text files). They will also learn how to make use of Master Pages to provide a consistent look and feel to their applications and how to use the Web.config file to configure their applications. They will also learn how to add membership features to their web applications, allowing users to log in with personal accounts and see content tailored directly to them.

The course is suitable for both C# and VB (VB.NET or later) developers.

Please note this course only covers ASP.NET Web Forms on .Net Framework. It does NOT cover ASP.NET MVC, .NET 6 or .NET CORE

Students are expected to have experience of either C# or VB (VB.NET or later). Those who do not may want to consider the Programming with C# or Programming with Visual Basic courses. Some understanding of HTML will also be an advantage.
